Hi, I have a problem with resizing images.
What happens is that if you upload a file larger than the stated parameters, the image is cropped, then saved at 100% quality.
So if I upload a large jpeg which is 272Kb. The image is cropped by 100 odd pixels. The file size then goes up to 1.2Mb.
We are saving images at a 100% quality. I assume that this is what is causing the problem. The image is exported from Photoshop at 30% quality which reduces the file size. Resaving the image at 100% quality creates the same image but I assume with a lot of redundant file data.
Has anyone encountered this before? Does anyone have a solution?
This is what we are using.
$source_im = imagecreatefromjpeg ($file);
$dest_im = imagecreatetruecolor ($newsize_x, $newsize_y);
imagecopyresampled (
$dest_im, $source_im,
0, 0,
$offset_x, $offset_y,
$newsize_x, $newsize_y,
$sourceWidth, $sourceHeight
);
imagedestroy ($source_im);
if ($greyscale) {
$dest_im = $this->imageconvertgreyscale ($dest_im);
}
imagejpeg($dest_im, $save_to_file, $quality);
break;
